Am having some movement of gas in my bladder some painful and discomfort, also having discomfort in my esophagus, please help?

Need examination: You are experiencing what we call disparate symptoms meaning that they do not seem related. "Stomach ulcer"is a condition that is not easily self-diagnosed and requires significant expertise. This, of course,may be related to your esophageal discomfort but maybe not. "Gas in the bladder" is probably a misconception and the advice here is to see a qualified physician to sort this all out.
